Mehmood died in 2004.
"It's a tribute to Mehmood bhai on his 10th death anniversary. 'Bombay To Goa' is an evergreen comedy and everyone can relate to the film so, we thought we must re-release it," Anwar told IANS.
Released in 1972, S. Ramanathan directed "Bombay to Goa" was an adventure-comedy, which saw Mehmood teaming up with Amitabh Bachchan, Shatrughan Sinha and Aruna Irani in the cast.
"As far as the re-release date is concerned, we are still figuring that out. We will either release it before the IPL (Indian Premier League, which starts April 16) or after the IPL as we want to do complete justice to the film."
One of the star comedians of the late 1960s and 1970s, Mehmood is known for his rib-tickling performances in "Padosan", "Love in Tokyo", "Aankhen", and "Johar-Mehmood in Goa". He also directed films like "Kunwara Baap".
Talking about his brother's work, Anwar said: "While comedy is being explored really well today, but during his time he alone explored comedy."
On April 12 Anwar plans to organise a special screening of the film.
"Amitabh Bachchan will be attending the special screening of 'Bombay To Goa' on April 12. Besides Amitabh Bachchan, many other people have agreed to attend the special screening," said Anwar who was seen in films such as "Sadhu Aur Shaitaan" and "Saat Hindustani".
